Our users rate Reverb
Up for sale is an iconic Mesa/Boogie TriAxis rack tube preamp, a true staple of '90s guitar tone.
Good shape but some signs of use (see pics please)
This unit is an original vintage piece (motherboard stamped MESA TX4 C 1992, integrated circuits with 1993 date codes). It is in excellent aesthetic and functional condition, fully ready for studio tracking or live performances.
Specs & Version (V2 No-Fat / Early Recto Board Specs & Version (V2 No-Fat / Early Recto Board):
This TriAxis is an early V2 model featuring the highly desirable factory-original TX4 Recto Board(PCB stamped MESA TX4 C ©1992 with 1993 date codes).
MIDI Continuous Control (CC): Full support for real-time parameter tweaking via MIDI expression pedals.
Pre-Fat Mod / Original Recto Sound: Features the original, un-modified Lead 1 Red circuit (Recto Board). Unlike later "Fat Mod" (Phat Mod) revisions, which added extra low-end that could sound muddy, this version delivers the iconic, tight, aggressive, and punchy Dual Rectifier tone preferred by most rock and metal players.
Service Details & Replaced Components:
To ensure maximum reliability, dead-quiet noise floor, and optimal sonic performance, this unit underwent a complete power supply section recap carried out by a professional tech:
High-Voltage Filter Capacitors (B+): Replaced with fresh JJ Electronic 30µF / 500V axial caps (secured with anti-vibration silicone per shop standards).
Low-Voltage Filter Capacitors: Replaced with high-quality fresh electrolytics (4700 uFand 3300 uF) in the regulation stage.
Original Components Status:
Audio Circuitry & Logic: All signal components (VTL optocouplers, film caps, CD4053/74HC logic ICs) and Motorola voltage regulators are 100% factory original.
Tubes: Loaded with tested, fully working 12AX7 preamp tubes.
This recap is a major plus: the power supply section is practically brand new, so you won't have to worry about the chemical degradation typical of 30-year-old original caps.
Will be packed securely with heavy-duty padding and shipped fully tracked and insured. Feel free to reach out with any questions or if you need additional high-res photos!
